Manual Calculation

Don't know your IVs? No worries. You can still figure out your Hidden Power type by testing it on various Pokemon. This is mainly for FireRed/LeafGreen users who don't have wild Kecleon to test against.

Now test out your Hidden Power on a Normal/Flying-type, like a Pidgey or Taillow.
It's not very effective - your type is BugThe opposing Pokemon is unaffected - your type is GhostIt deals regular damage - your type is Dark

Your Hidden Power is now either Psychic or Fighting. At this step, test against a Gastly or a pure Poison-type like Ekans.
